Description

  The present invention relates to a storage box that can prevent furniture from falling over by being sandwiched and fixed in a gap between the furniture and a ceiling.

  Conventionally, as a method of preventing furniture from falling down due to an earthquake, a gap between the upper surface of the furniture and the ceiling has been filled. As a method of filling the gap, there is a method of sandwiching a telescopic pole between the gaps. However, this method has a problem that the pole is exposed and the space on the upper surface of the furniture cannot be used effectively. On the other hand, as in the device described in the following patent document, it is desirable that the box that can be expanded and contracted is sandwiched between the upper surface of the furniture and the ceiling so that the inside of the box can be used as a storage space.

Japanese Patent Laid-Open No. 8-140754 Japanese Unexamined Patent Publication No. 2007-50198 [0057], FIG. Utility Model Registration No. 3028930 Japanese Patent No. 3799504

By the way, as shown in FIG. 1, FIG. 2, and Patent Document 3 of Patent Document 1, as a method of fixing a box that can be expanded and contracted, a separated wall surface is provided between the upper box and the lower box, The method of changing the joining position in the vertical direction with the lower box requires a sufficient strength of the wall surface, and there is a restriction that it is not desirable to form the cardboard or the like. Further, in the method of providing a bent plate body inside and changing the angle of the plate body as in Patent Document 4, the bent plate body portion cannot be used as a storage space and is wasteful.
On the other hand, as shown in FIG. 5 of Patent Document 1 and FIG. 12 of Patent Document 2, rods that can be expanded and contracted are provided at the four corners inside the box, thereby fixing the expandable and contractible box at a predetermined position. The structure is desirable without being affected by the material of the box.
However, the rod body that can be fixed and stretched is formed so that it can be expanded and contracted by inserting the rod body or pipe body into the pipe body, so that the length range is from the length of the outer pipe to about twice this. There is a problem that the length is limited.
In view of such a problem, the present invention has an object to increase the applicable height range while using a rod body that expands and contracts in a storage box that has a function of preventing furniture overturn using a box body that expands and contracts. To do.

In order to solve the above problems, the present invention has the following configuration.
The invention according to claim 1 is a box having no upper surface, a lower box having an opening formed on the front surface, and a box having no lower surface having a size such that the outer peripheral side fits into the inner peripheral surface of the lower box. The inner box formed lower than the height of the lower box, and is formed to be stretchable by inserting a rod-like body into the pipe body, and is formed to be fixable at an arbitrary extension position. 4 expansion rods arranged upright at the 4 corners of the upper surface of the middle box or the 4 corners of the bottom surface of the lower box, and a box body without a lower surface having a size such that the inner circumferential surface fits on the outer circumferential surface of the lower box. And a furniture fall prevention function storage box having an upper box formed higher than the maximum length of the telescopic rod.
According to a second aspect of the present invention, in the storage box with furniture fall prevention function, at least a side peripheral surface of the upper box is formed of cardboard. The invention according to claim 3 has the furniture fall prevention function. In the storage box, a horizontal member is fixed to the upper and lower ends of the telescopic bar, and is provided at the four corners of the upper surface of the middle box or at the four corners of the bottom surface of the lower box, and is adjacent to the opening surface of the middle box. Two horizontal members on the lower end side are provided so as to contact two sides of the upper surface or two sides of the bottom surface adjacent to the opening surface of the lower box.

In the invention according to claim 1, by placing the middle box in the lower box and disposing the telescopic rod thereon, the entire height of the middle box can be increased in addition to the maximum length of the telescopic bar. If you want to lower it, you can reduce the overall height to the minimum length of the expansion rod by placing the expansion box on the top surface of the upper box or removing it and placing the expansion rod on the bottom surface of the lower box As a result, the height can be adjusted beyond the range of the length of the telescopic rod. In addition, when the lower surface of the upper box is lower than the lower surface of the lower box in a state where the height is lowered, the height may be adjusted by appropriately cutting the side surface of the upper box.
According to the second aspect of the present invention, when the side surface of the upper box is formed of corrugated cardboard, the work can be performed relatively easily when the side of the upper box needs to be cut.
According to the third aspect of the present invention, the height adjusting operation can be simplified because only two heights need to be changed when the height is adjusted by using two left and right extendable bars.

It is a disassembled perspective view of the storage box with a furniture fall prevention function concerning an embodiment. (A) is a longitudinal cross-sectional view which shows the state which installed the expansion-contraction rod in the upper surface of the inner box of the storage box with the furniture fall prevention function which concerns on embodiment, (b) is the state which installed the expansion-contraction rod in the bottom face of the lower box FIG. It is a perspective view which shows the other example of an expansion-contraction rod.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a perspective view of a storage box X with furniture fall prevention function (hereinafter referred to as storage box X) according to this embodiment, and FIG. 2 shows an exploded perspective view of the storage box X. The storage box X includes a lower box 10, a middle box 20, an upper box 30, and an extendable bar 40.
The lower box 10 is a box with an open upper surface formed of cardboard, and an opening 11 reaching the upper edge is provided on the front side. A non-slip sheet 12 made of rubber is attached to the bottom surface of the lower box 10.
The inner box 20 is a box body having a lower surface formed of cardboard, and an opening 21 reaching the lower edge is provided on the front side. The height of the middle box 20 is set lower than the height of the lower box 10.

The upper box 30 is a box body having a lower surface formed of cardboard, and an opening 31 reaching the lower edge is provided on the front side. In addition, a roll curtain 33 is fixed to the upper front side of the upper box 30 and a non-slip sheet 32 made of rubber is attached to the upper surface. The telescopic rod 40 is expanded and contracted by nesting a thin pipe inside the pipe body. The inner pipe is formed so as to be able to advance and retreat with respect to the outer pipe by a screw mechanism, and can be fixed at an arbitrary position. Four telescopic bars 40 are provided. As a means for fixing the pipe inside the telescopic rod 40, various methods such as a method of penetrating the inner pipe vertically with a screw from the side surface of the outer pipe can be adopted. Further, the height of the upper box 30 is formed to be larger than the maximum length of the telescopic rod.

  Next, a method of using the storage box X having the above configuration will be described. The storage box X is provided so as to fill a space between the ceiling to be prevented from falling and the furniture. When the distance between the upper surface of the furniture and the ceiling is long, as shown in FIGS. 1 and 2, the middle box 20 is placed in the lower box 10, and the upper box 30 is further fitted outside the lower box 10. Then, the four telescopic rods 40 are arranged upright so as to connect the four corners of the upper surface of the inner box and the four corners of the inner upper surface of the upper box 30. FIG. 3A shows a longitudinal sectional view taken along a plane parallel to the front surface of the storage box in this state. In this state, the storage box X is arranged on the upper surface of the furniture F, and the four telescopic bars 40 are extended and fixed so that the upper surface of the upper box 30 presses the ceiling C. This completes the installation of the storage box X, but the strength can be increased by fixing the lower box, the upper box, and the inner box with an adhesive tape or an adhesive inside the lower box and the upper box. desirable. By arranging the middle box below the telescopic bar 40 in this way, the storage box X can be set higher than the maximum length of the telescopic bar 40 by the amount of the middle box. Further, by providing the inner box, the upper surface of the inner box serves as a partition in the storage box X, so that convenience in storing an object is increased.

  On the other hand, when the distance between the upper surface of the furniture and the ceiling is relatively short, the middle box 20 is overlaid on the upper surface of the upper box 30 or the middle box 20 is removed and the upper box 30 is fitted outside the lower box 10. The four telescopic rods 40 are vertically positioned so as to connect the four corners of the inner bottom surface of the lower box 10 and the four corners of the inner upper surface of the middle box 20 or the upper box 30. In this state, if the side surface of the upper box 30 is too long, the side peripheral surface of the upper box 30 may be appropriately cut and adjusted to an appropriate length. FIG. 3B shows a longitudinal sectional view taken along a plane parallel to the front surface of the storage box in this state. In the figure, a portion 35 indicated by an imaginary line in the side peripheral surface of the upper box 30 is cut. In this state, the storage box X is arranged on the upper surface of the furniture F, and the four telescopic bars 40 are extended and fixed so that the upper surface of the upper box 30 presses the ceiling C. Then, if necessary, the inside is reinforced with an adhesive or an adhesive tape. In this manner, the storage box X can be set to a height that is almost as low as the length of the telescopic rod 40 most contracted by using the storage box X so as to eliminate the height of the middle box 20 minutes.

  In the above embodiment, four rods having point-like ends are used as the elastic rod 40. However, like the elastic rod 40A shown in FIG. 4, horizontal members 40Aa are provided at the upper and lower ends. , Two left and right telescopic bars 40A are sufficient on the left and right.
